[0/7] Input: cyttsp - First round of modernizations

Message

Linus Walleij March 30, 2021, 8:54 a.m. UTC

This fixes some issues I had when getting the CYTTSP
(also known as CY8CTMA340) to work with a modern device
tree and userspace.

The device stands out as there are no in-kernel users of
either platform data nor device tree.

I am going to submit a device tree client, if you have
other concerns, then step forward now.

With these patches the touchscreen works fine with
PostmarketOS on the Ux500 HREF using Wayland and Phosh
as UI.

This work is really being done to get a baseline for
refurbishing the PL022 SPI driver but sometimes you
have to fix a bunch of stuff.
